Happy, happy, oh my friend Blow out candles once again Leave the presents all inside Take my hand and let's take a ride Backwards down the number line You were eight and I was nine Do you know what happened then? Do you know why we're still friends? Laughing all these many years We've pushed through hardships tasted tears We made a promise one to keep I can still recite it in my sleep Every time a birthday comes Call your friend and sing a song Or whisper it in to his ears Or write it down, just don't miss a year You decide what it contains How long it goes but this remains The only rule is it begins Happy, happy, oh, my friend You decide what it contains How long it goes but this remains The only rule is it begins And all my friends come Backwards down the number line All my friends come Backwards down the number line All my friends come Backwards down the number line All my friends You decide what it contains How long it goes but this remains The only rule is it begins Happy, happy, oh my friend You decide what it contains How long it goes but this remains The only rule is it begins And all my friends come Backwards down the number line
